MICHIGAN CLOSURE Application filed April 26,

l ext-ent, and to effect a sealing engagement of the closure with the support through such rotation,

Still another object is to provide. a novel quick detachable hinge connection between 5 a closure and its support.

A further object is to provide an improved closure for t-he filler tube of a radiator, and to adapt said closure to replace the filler tube caps of standard radiators.

These and various other objects the invention attains by the construction hereinafter described, and illustrated in the accompanying drawings, wherein:

Figure l is a diametrical vertical section of still another alternative construction.

Figure 2 is a similar view, showing the cap member in closed position.

1Figure 3 is a horizontal sectional View taken on the line 3 3 of Figure 2.

Figure 4 is a plan view of the same with the cap member in open position.

Figure 5 is a view of the same in side elevation.

Figure 6 is a fragmentary section on line 6-6 of Figure 3.

In Figures 1 to 6 inclusive the hinge is fully concealed in the closed position of the closure. in this constructionan adapter ring` 39 is screwed into the collar 40 of the filler tube 4l, From the flange 42 of said adapter ring a pair of diametrically opposed lugs 43 and 44, project outwardly, the lug 44 having a T- shape. Said lug forms a hinge member to mount the flanged cap 45. In the flange of said cap, adjacent to the top thereof a pair of diametrically opposite. grooves 46 and 47 are interiorly formed, to receive the lugs 43 and 44, said grooves being slightly inclined so as to cause said lugs to exert a downward pressure at opposite points ot the cap responsive 1926. Serial No. 104,759.

to a suitable rotation of the cap. From the lower end of the groove. 47 extends a guide way for the T-head of the lug 44, which guide way provides pockets 48 engaged by the head opening from said groove toward the lower edge of the caprmember, said pockets being one at each side of a groove 49 in which the stem of said lug may travel; 50 designates an entrance way .for the lug 43 extending from the lower end of the groove 46 to the lower ad of the flange of the cap. A gasket ring 5l inserted in the upper portion of' the cap member is adapted to be compressed against the flange 42 as in the first-described construction.

It will be noted that provision made for hingedly mounting the closure and to subject said closure, when rotated, to a kpressure whereby it is firmly seated in sealing engagement with a suitable support.

It is to be understood that the uses of the inver-tion have been merely exemplified by this disclosure, and that the invention is capable ot many ruses not requiring enumeration herein.

What I claim is:

l. The combination with a container havV ing an opening, of a ring rprojecting from said container surrounding said opening, a closure for said opening rotatable in its closed position around said opening to a limited extent, and having anrannular liange, and means carried by said ring and engaging said flange establishing a hinge connection between the closure and container and subjecting the closure to a sealing pressure upon a predetermined rotation of the closure.

2. The combination with a container having an opening, of a ring projecting from said container around said opening, a closure for said opening flanged to enclose said ring, and means establishing a hinge connection between the flange of said closure and said ring, the said hinge connection being detachable upon rotation of the closure.

3. The combination with a container having an opening, of a ring projecting from said container around said opening, a closure for said openingsaid closure having a spiral shoulder thereon, and a member carried by CTI said ring` und attaching the closure'to said container, said ineinber adapting,` the closure to swing between its open and closed p A'o' in one Josition or rotation of the closure, end co-actinw *with said shoulder of the closure upon rotation from the specified position 1; press the closure into sealing engagement with the container.

The combination with a container het@ ing an opening, of a ring projecting' rointhe container around said opening', a closure for said opening` having a flange adapted torenclosr said ring; in the cl-osedvposition of said closure, the iiange of the closure being` formed oppositelj,T with spiral shoulders, and ineinbers project oppositely from sait ring coacting with said shoulders upon rotation of the closure in its closed position to subject the closure to s sealing' pressure, one of said projections further forming a hinge .mounting for the closure in one rotativeposition of the closure,

5. The combination with the iiller tube of a radiator, of an adapter ringjtting Within the mouth portion orn said tube, ineens securing' said adapter ring Within said tube, a detaciiable hinge connection between said adapter ring and closure and ineans operable upon rotation of the closure to subject the saine to a sealing` pressure.

6. The combinati-on with tlre filler tube or a radiator, of an adapter ring' secured to said tube, a. iianged closure for said tube adapted in its closed position for limited rotation with respect to said tube, and means hinging' the flange of said closure to said ring in one position of rotation o1c the closure, and sufojectiin;` the closure to a` sealing pressure in another of its rotative positions, said ineans being normally fulljvT concealed by the said closure.

rEhe combination With a container havingv an opening', of a ring projecting roin said container surrounding said opening; havinp a spiral shoulder thereon, a closure for id opening und projections carried by said and engageable with the shoulder aforesaid to subject the closure to a sealing pressure upon rotation of the saine.

8. rEhe combination with a container having' an opening, of a ring' proiectingl from said container surronndin-- said opening, aclosure adapted for a limited rotation around said opening, and a member carried by the ring and engaging the closure exercising a hinge function in one rotative position of the closure and subjecting' the closure to a sealing pressure in another rotative position ot the closure, said ineinber and the connection thereof to the closure being fully concealed Lin ythe closed position of the closure.

9. rihe combination Witha container having an opening, of a ring projecting :troni said container around seid opening, a flanged closure for said opening, and ineans establishing CECL E. CRilRi.
